What a missed call actually costs you
You can run the arithmetic in two minutes with your own call log, and the number is usually bigger than you would guess.
SHORT ANSWER
A missed call costs you the job it would have become. To find your number, multiply four things: missed calls per month from your call log, the share that were real prospects, your close rate on prospects you speak to, and your average job value. The fix, from cheapest up, is answering more calls, texting back automatically within seconds, and having an AI receptionist answer every call.

Ask how many calls you missed last month and you may have to guess. Ask how many jobs you lost to a competitor and the guess gets even worse. The two questions are the same question, and your phone company has already done the work of answering it.
The number nobody has
Every mobile carrier and every VoIP provider keeps a call log with an answered flag. It is usually three taps away in an app you already pay for. Pull last month. Count your inbound calls. Count how many you answered. For a busy crew that spends the day on job sites, the gap is rarely a rounding error.
The first time you see that number written down, the reaction is almost always the same: that cannot be right. It is right. It is just that your missed call leaves no evidence. There is no angry email, no bad review, no customer standing in your office. The job simply happens somewhere else, and the loss shows up as a quiet month you blame on the season.
The arithmetic
Four numbers, and you probably know three of them already.
- Missed calls per month. From the call log. Not an estimate.
- How many were prospects rather than suppliers, spam or your mother. Be conservative — call it half.
- Your close rate on a prospect you actually speak to. Use your own, not an industry average.
- Average job value. Revenue divided by jobs. Use the plain average, not the one job you like telling people about.
Multiply them. For example, if you miss 90 calls a month, half are real prospects, you close 40%, and your average job is $4,180, you are leaving roughly $75,000 a month on the table. Even if every assumption in that chain is twice as generous as reality, the remaining number can still be larger than any line item in your marketing budget.
Your call log may be the most honest marketing report you own, and almost nobody opens it.

Why voicemail stopped working
Because nobody leaves one. Under about thirty, voicemail is a thing that happens to other people; your caller reaches your greeting, hangs up, and taps the next result. They are not being rude. They have four more contractors on the screen and a ceiling that is actively dripping.
Worse, your customers most likely to hang up are the ones you want most. Emergency work has the shortest patience and the highest margin. The homeowner comparing quotes for a $400 repair will wait for a callback. The one standing in two inches of water will not.
The three fixes, in order of cost
Answer more calls. Obvious, and mostly not available. You are on a roof. Hiring someone to sit by a phone is a full salary, and they go home at five, which is when the emergency calls start.
Text back automatically. When your call goes unanswered, an immediate text goes out from the same number: an apology, your name, and one direct question. This works for a boring reason: your customer is still holding the phone. They have not moved on yet, and a text that arrives in seconds catches them before they dial the next name.
Have something answer the phone. A voice agent that knows your services, your pricing ranges and your service area can book the estimate, dispatch the emergency, or schedule the callback — at 7:42 on a Saturday evening, when your competitor is at dinner and their answering service is taking a message nobody will read until Monday.
What to do Monday
Open the call log. Count the missed calls. Do the multiplication above and write the number on something you will see again. You do not have to buy anything to do that, and you should not decide what to fix until you know what it is worth.
Then decide whether your number justifies twenty minutes on a call.
